If you increase the frequency of a sound wave four times, t<span>he speed will increase four times. The correct option among all the options that are given in the question is the first option or option "A". This also shows the frequency and speed of the waves are directly proportional to each other. I hope it helps you.</span>
Answer:
Setting goals keeps students focused on desired outcomes and provides a clear direction for success
If we assume that the acceleration is constant, we can use on the kinematic equations:
Vf = Vi + a*t = 15 + 3*4 = 27 m/s

Answer:
Applied voltage should be 13.5396 kV
Explanation:
The charge stored by a capacitor when subjected to a potential difference 'v' across it's plates is given by
Solving for V we get
thus to store a charge of 0.11mC we solve for V as follows
Applying values we get
